PSI Parts

You are looking at around a 9kg difference from a metal bonnet to a carbon fibre bonnet. Keep in mind that GTRs had an aluminium bonnet so the weight reduction is not as great.

Unfortunately none for a R34 GTR at the moment.

There is a bit of info regarding the 40th anniversary on our Project Car page, this is being updated at the moment so stay tuned. http://www.psiparts.com.au/project.htm

Here is the link on our website: http://www.psiparts.com.au/detail.htm?ProductID=R33S-EXHS-CF

I'm also eyeing off this: http://www.transquip.com.au/product.aspx?ID=5893

Hey mate, We have some in stock. Are you after frp or carbon fibre?? Cheers, Shane

Anyone have input on the ACL Pistions?

See here for the manual: http://www.psiparts.com.au/downloads.htm

Why are people insisting on using a 040 for a lift pump? The stock pump is fine and will help reduce heat by reducing the pressure the fuel is under from the time it begins it's journey from the main tank.

What sort of rubber fittings would he be using? Even push on fittings for rubber hose are available very cheaply in alloy.

Great thread. SK is using the factor of 1.2 to convert from hp to bhp (brake horsepower). Thus 300rwkw = 402rwhp = 480 bhp Just to rehash the formula in another way: A = power figure in rwkw B = A * 1.3 * 1.2 = power figure in bhp Wastegate size in mm = B / 11 To confirm wastegate size we apply the boost correction by using the following: C = wastegate size in mm D = intended boost pressure in PSI E = D / 14.5 = boost pressure in bar Confirm = wastegate size / E * 1.4 The only problem I have is where the figure of 1.4 comes from, I assumed atmospheric pressure however thats only 1.01325. Also there has been various figures in PSI used (19,20) As 1.4bar = 20.31 I'm a little stumped. Just on a side note, I'm keen to hear people's thoughts on mounting the wastegate directly to the exhaust housing as done by ETM, as they claim it improves wastegate efficiency and stabilises boost pressure much better.

As far as hose choices go Teflon should be the best (although some further investigation into long term-use and thorough testing should be done before i make any statements), and reduces fuel vapour seekage, to me it sounds like a viable choice as it gives you the flexibility of a variety of fuels and eliminating one of the worst factors when it comes to aftermarket hoses. Can you please clarify if it was the fittings or the hoses?

I might have missed it the results (although I thought I read all 5 pages), but I take it was a lot easier with E85 and what was the end deal whether or not the car would be required.

So has anyone done the test with E85 yet?

I'll take the gear stick surround if you are willing to post to Sydney. PM me with details.

Drop us a line at [email protected] about the pods, we should have some in stock.

I'll take the Gear stick surround. I'm away at the moment so send me payment details via PM.

I'm interested but won't be in a position to buy for atleast 2 months as I am still overseas. Just a few questions; - Is the engine in a car currently? - What computer has been running this? - Am I able to see the engine on either an engine or chassis dyno before purchase? (to verify claimed power level) - How many km's since the build? and type of events the car has been driven in?

Although it is rated at 1000kg, (from memory) in Australia the jack has to support three times the rating actually stated. Pics please people...

I'm currently overseas and don't have any contact with the Snap On dealer, can anyone who has one able to take some pictures for me?

We will match any competitors price on this kit!! PSI Parts

The direction of the vents shouldnt matter, it is more about the size, location and angle of them. This is for pedestrian safety. I'll dig up the diagrams and rulings i have somewhere to see if we can make any sense of it.. Can you please confirm what state you are in? I'm interested to know about the demerit points for having a defective vehicle?? Yes we have sold some hoods into QLD. Yes they are different from state to state which is the most ridiculous thing.

Hey, We have the full kit which consists of: - Front Bar - Hood - Front Fenders - Side Skirts - Rear Bar - Rear Fenders The kit is in stock and can be viewed at our workshop in Dandenong. Price is $1950. Regards, PSI Parts

Hi Guys, My name is Shane and I'm the General Manager of PSI Parts (www.psiparts.com.au). I will try to clear up a few mis-conceptions about frp and carbon fibre hoods. When you replace the bonnet with either of the above materials the whole vehicle needs to be complied. There is NO such thing as an ADR approved bonnet, despite what some people claim. This is because there is no set ruling for after market hoods Australia wide. We sell a wide variety of carbon fibre and frp hoods and trunks and our customers have not reported any trouble with the police. I have had numerous accounts from customers of how they were given a Defect Notice for multiple things but the carbon bonnet and boots were ignored. This is because there is NO LAW against them, having set that, there is no law stating they are legal as well. They lye in the grey area of the law. The law does however state that if you change any panels forward of the firewall you need a Compliance Certificate. We have contact many state and territory road authorities and have not been able to get a clear statement on what we can do to make them legal. Also to clear up a few rumours going around about carbon fibre, it DOES NOT shatter and cut peoples heads and arms off. It is a very strong and stable material and in fact will hold up very well in the case of an accident because of the construction method. I believe these come about from people who know very little about the material and its properties. After all they do make Formula 1 monocoques from carbon fibre which need to withstand 300+ Km/h impacts with out killing the driver. If anyone has any questions I will be glad to try and answer them.

Nobody else had any experience with them?
